The difference between ferro silicon inoculant and silicon barium inoculant
Inoculant is a very important metallurgical material. There are different classification methods for inoculants according to their composition and use. According to their composition, inoculants include ferro silicon inoculants, silicon-barium inoculants, rare earth inoculants, and carbon inoculants. Among them, ferro silicon inoculants and silicon-barium inoculants are two common inoculants. What is the difference between these two inoculants:
Since ferrosilicon inoculants have different index contents, their use value and market price are also different. The inoculation treatment effect of 45 ferro silicon inoculants is poor, and the use cost of 85 ferro silicon is too high, so now steel mills and foundries often use 75 ferrosilicon and 72 ferrosilicon as inoculants. Ca and Al in ferro silicon have a great influence on the inoculation effect, among which Ca has a greater influence and has a stronger graphite ability when it is greater than 0.5%. The aluminum content of 75 ferro silicon is 1.5%, and the aluminum content of 72 ferro silicon is 2%.
Silicon barium inoculants are mainly used in the production of gray cast iron and ductile iron. Silicon-barium inoculants can increase the number of graphite nodules in ductile iron; they can reduce the tendency of white cast iron, refine grains, promote graphitization, and improve graphite morphology in gray cast iron. In addition to improving mechanical properties, silicon-barium inoculants also have strong anti-degradation ability. The most commonly used silicon-barium inoculants are those containing 2-4% barium. Silicon-barium inoculants are generally 0.2-0.8mm flow inoculants, with particle sizes of 1-3mm and 3-8mm.
